Beatorio! A Music Sequencer drum machine synth

[Tayday]

Built a music sequencer/drumkit without using belts and wanted to share. This particular BP can be a 10 track 16 step sequencer or a 5 track 32 step sequencer. You can also mute individual tracks. Change the volume or sound via default Factorio "speaker" on each track. Inspired by fruity loops/DAWS and physical synthesizers. My hope is with the new expansion they add more control and functionality over the "speaker" component so you can dynamically change sounds/volume/pitch with circuits etc etc... I'd love to have a dynamic/rng beat being generated based on factory statistics.

That's funny, it look like the one i did , like colors and way it works and all x) viewtopic.php?f=193&t=112834

You can already change sound using circuits to generate dynamic beat based on factory statistics !

I hope those possibilities will be extended too !

I just saw your post! I was about to reply to it!

You can change the speaker sound/pitch based on an input value??? really??? how??? I made this BP back in 2023 I have to revisit it now hahahhaha

You can tick the box " signal value as pitch" and it chooses the note based on its ID, with the first one being 1.

I couldn't find one such things when i searched for it , i'm glad to see it on factorioprints now

Ah right... the pitch can be changed but can the actual sound be changed with a signal?

Not sure what you mean ? You can't change the instrument, only the note with vanilla speakers.

After looking at your posts I wanted to ask you a question. My biggest hurdle was getting the sequence to loop seamlessly...let me try to explain hopefully. Based on Factorio "ticks" I was counting up from 1 to 16 or 0 to 15 and then resetting the count, to assign the position of where the beat is currently at. However when the number sequence looped back around from the end position(lets say 16) to 0 or 1 it was always a millisecond off and sounded incorrect. If I remember correctly there was always a split millisecond with a null or empty value after the reset, that would mess up the seamless loop.

I tried so many mathematical solutions to try and get it to "wrap" smoothly, it never worked. The only way I got it to work was just to have it "count up" infinitely and just add that value to the current "position". So in a way its not looping programmatically per say its just counting up and dynamically changing the number of each position.....until...I guess Factorio runs out of integers? ....Hope that made sense

Yea that's what I mean, I hope one day you can change the instrument, or even volume.

It may have to do with the time taken by the combinators to do the operation, it takes 1 ticks so if you have a different chain of operation occuring when reseting, it may happen that it introduces a delay of 1 tick and depending on the music played, it can be heard

Yea that's what I mean, I hope one day you can change the instrument, or even volume.

There is this mod which allows to do so :
https://mods.factorio.com/mod/musical-speaker-fixed
But it's a little more complicated to use than vanilla speakers because you can also control "for how long the sound is playing", it introduces a new speaker

That makes sense, you're limited by ticks and the count "reset" requires a tick.....THANKS!

Thanks I'll check out this plugin!
